Hello, I have searched the forums and found others with similar problems, but nothing that sounds exactly like what I'm experiencing, so I am starting a new post. I hope someone can help me.
The HDD on my MacBook Pro died. I replaced it with a Crucial MX100 256 GB. I formatted the drive via Apple's Internet Recovery, and then tried to install the OS several times, but the installation failed every time from a download time out. So, I went to an Apple store so they could install the OS for me directly from their in-store network. Twice, they tried installing the OS, and both times the installation completed the process and gave an error message that the installation had failed. The techs verified that everything in the computer was working fine and they could find nothing wrong with the drive itself. And yet, the problem persists.
One tech suggested that because the drive was formatted in FAT32 that maybe that was the problem but he didn't sound too confident. Does anyone know what the problem is or how I can continue troubleshooting this problem? Thank you in advance.

Perhaps you might want to try the same as I suggested in this thread:
Try repartitioning and reinstalling OS X when the SSD is connected to the Macbook Pro with a USB inclosure/interface and then see if you get any further than you did when it was installed inside the Mac.

Alex, thank you for the advice. I don't have experience with this. Can you please recommend the equipment I need to externally mount your drive and connect it via USB? Thank you very much.

Summit, thanks for the heads-up. I'm going to try what Alex said, but I will keep your thoughts in mind as well, especially if things are not going as planned. I appreciate you trying to help me.

Is this what you mean?
Something like that should be o.k. Perhaps if you want to use it later for installing a backup drive, it might be better to get a USB 3.0 enclosure for a few dollars more.
You didn't mention what year/model your Macbook is, I'm guessing 2011 or 2012 since it appears to support internet recovery?
Please note on that thread I linked to earlier, the thread starter found that he could get the SSD working by placing some insulation between the SSD and the cable. Perhaps something like that works for you too, but might not be a good long term solution.
Let us know how you get on.

**** ask them to install Yosemite on an Apple SSD?
Do they have any Apple SSDs in the store just hanging around for people to test?
I doubt they would order a replacement Apple SSD just for testing a Mac that originally came with a Hard Disk.
Perhaps they would test with a HDD?
Two things should be mentioned about those Apple SSDs.
1. To the best of my knowledge you can't purchase one without buying a new Macbook Pro.
2. The ones that you could order with the non-Retina Macbook Pro aren't very good by modern standards.
If you search you might find SSD for 2.5 inch SATA, model numbers Apple SSD TS256C and Apple SSD TS512C.
Note: The same numbers appeared to be used for some Macbook AIr, which is a different SSD form factor.
But assuming that you can find one of the above in 2.5 inch SATA format, it might be worth look at the results that people have been getting from these Apple SSDs.
You can also search for OEM part numbers such as theses:
You will notice that these are restricted to SATA-II speeds.
So perhaps an Apple SSD would work, because it is a slower SATA-II drive and it might work well enough, because the SATA interface doesn't have to work at SATA-III.
But a late 2012 macbook pro should support SATA-III in the HDD Bay if the SATA cable is good and there are no other faults. Thousands of people have swapped the original apple drive for a SATA-III SSD.
**** If it works purchase the Apple SSD.
To the best of my knowledge that is not possible, but I'm happy to learn something new here.
Please provide a link if you find an Apple store selling these SSD without purchase of a new Macbook.
But I suspect that Apple hold a limited number of spares reserved for the people who have Apple Care and an original Apple SSD.
**** It will also confirm that the Sata cable is OK.
OK at SATA-II speeds perhaps.
